Jamal has 1240 song on his mp3 player, and 40% of the songs are rock songs. how many are not rock songs?

Colt1911 [192]

Total songs = 1240
Rock songs = 40%
Songs that are not rock = 100 - 40 = 60%

It would be: 1240 * 60% = 1240 * 0.60 = 744

In short, Your Answer would be 744

2(3/5x+3). How would I get that answer

Airida [17]

Answer: $\frac{6}{5}$ x + 6

Step-by-step explanation:

We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.

Given:

2(3/5x+3)

Distribute:

2 * (3/5x) + (2 * 3)

6/5x + 6

Answer:

$\frac{6}{5}$ x + 6
